Problems solved by technology

However, the self-discharge rate of the supercapacitor is high. In the idle state of shading, the supercapacitor will continue to discharge. When the supercapacitor discharges its own power, the lithium battery will supply power to the supercapacitor to continue discharging, and so on until Both the lithium battery and the supercapacitor are fully discharged, resulting in a waste of electric energy

Embodiment Construction

[0041] The following is attached Figure 1-5 The application is described in further detail.

[0042] In wireless sensor network technology, wireless sensor network nodes account for most of the Internet of Things nodes. Wireless sensor network nodes have sensing, processing and communication functions, and need to consume a lot of power. The power supply method of traditional wireless sensor nodes Disposable batteries are used, but due to the limited size of the nodes, the use of disposable batteries for power supply cannot provide long-term functions for the nodes, and due to the large number of nodes, and many of them are distributed in places that are inconvenient for manual replacement, so in recent years, environmental energy harvesting technology has emerged. A new approach for wireless sensor node functionality.

[0043] The embodiment of the present application discloses a photovoltaic micro-energy collection system. refer to figure 1, the micro energy harvesting s...

Abstract

The invention relates to a photovoltaic micro-energy acquisition system and a hybrid energy storage automatic charging and discharging control method thereof. The photovoltaic micro-energy acquisitionsystem comprises a photovoltaic battery, a light energy acquisition controller and an energy storage module used for supplying power to a load; the energy storage module comprises a rechargeable battery, a super capacitor and a super capacitor charger; the energy storage module further comprises a first output detection unit, a second output detection unit and a third output detection unit. The first output detection unit judges whether output power exists on the super capacitor or not; the first output detection unit controls the photovoltaic battery to charge the rechargeable battery when the output power exists on the super capacitor. The second output detection unit whether output power exists on the super capacitor or not; the second output detection unit controls the photovoltaic battery to charge the super capacitor when the output power does not exist on the super capacitor. The third output detection unit judges whether output power exists on the super capacitor or not; and the third output detection unit controls the rechargeable battery to supply power to the load when the output power does not exist on the super capacitor. With the photovoltaic micro-energy acquisitionsystem and the hybrid energy storage automatic charging and discharging control method thereof of the invention adopted, electric energy waste caused by the self-discharge of the super capacitor canbe decreased.

Description

technical field [0001] This application relates to the field of new energy composite technologies, in particular to a photovoltaic micro-energy collection system and a hybrid energy storage automatic charge and discharge control method thereof. Background technique [0002] With the prominence of social energy and environmental issues, renewable energy sources such as solar energy and wind energy have attracted widespread attention. Since the output power of photovoltaic power generation is affected by external factors such as light intensity and temperature, the photovoltaic power generation has the characteristics of intermittent and randomness, which seriously affects the stability of power grid operation and power quality. In order to stabilize the fluctuation of photovoltaic output power, people have studied and adopted a photovoltaic-energy storage system, by storing the energy generated by photovoltaic power generation in the energy storage device, it can continue to ...
